# Agent Micro Cryptographic Hash

> Agent Micro Cryptographic Hash is a paid API for AI agents from agent-micro.annushka1190.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Computes a cryptographic hash of provided input data, returning the hash digest for integrity verification or fingerprinting purposes.

## Facts

- Endpoint: POST https://agent-micro.annushka1190.workers.dev/v1/crypto/hash
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agent-micro-cryptographic-hash-a365c516
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_9j0wsjZ-XL0dcq44biqGs

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-micro-cryptographic-hash-a365c516 -d '<json body>'
```

Example prompt: Hash the string 'hello world' using SHA-256 so I can verify its integrity — just give me the digest.

## When to prefer this

Choose this endpoint when you need a cheap ($0.002 USDC), low-latency, pay-per-call cryptographic hash computation without setting up any backend infrastructure. Ideal for AI agents that need on-demand hashing as part of a pipeline — e.g. deduplication, integrity verification, or fingerprinting — without managing keys or libraries. Prefer over self-hosted solutions when you want stateless, serverless hashing billed via USDC on x402.

## Known failure modes

- Missing 'input' field in request body returns validation error
- Unsupported hash algorithm specified returns error
- Malformed JSON body causes 400 Bad Request
- Network timeout on Cloudflare Worker edge node
- Payment not processed (x402 payment required) returns 402

## How this service works

Advanced micro-tools for AI agents: cryptographic randomness, text analysis, math helpers, date arithmetic, web metadata, and IP intelligence. All under $0.01 per request, paid in USDC via x402.

## Output

Returns a JSON object with an 'ok' boolean and the computed hash digest for the provided input. The digest can be used for integrity checks, deduplication, or fingerprinting.
